Thermostructural Numerical Analysis of the Thrust Chamber of a Liquid Propellant Rocket Engine. [PDF]
The numerical simulation of rocket engine thrust chambers is very challenging as several damaging phenomena, such as plasticity, low-cycle-fatigue (LCF) and creep occur during its service life. The possibility of simulating the thermostructural behavior of the engine, by means of non-linear finite element analyses, allows the engineers to guarantee the

Dataset of the experimentally measured heat transfer in the throat region of liquid rocket engine thrust chambers [PDF]
About 500 experimental heat transfer data taken from the open literature and relevant to the most thermally solicited area (i.e., the throat region) of liquid rocket engine thrust chambers, are collected and manipulated. This collection is the outcome of

Determination of Cyclogram for Liquid-Propellant Rocket Engine [PDF]
A vertical test stand based on launcher propulsion system was constructed and several tests for the determination of cyclogram were carried out. To make an accurate estimation, static and dynamic pressures were measured and analyzed. Especially, static pressure measurements using fast response sensors without extension tubes were used to determine ...

Fundamental Concepts of Liquid-Propellant Rocket Engines [PDF]
The engine of a rocket vehicle is a machine which produces thrust by accelerating a gas flowing through the machine. The reaction to this acceleration is the force which drives the vehicle. The amount of thrust generated depends on the mass flow rate of the gas moving through the engine and on the exit velocity of the gas from the nozzle. The gas flow,

Liquid-Propellant Rocket Engine Throttling: A Comprehensive Review [PDF]
Liquid-propellant rocket engines are capable of on-command variable thrust or thrust modulation, an operability advantage that has been studied intermittently since the late 1930s. Throttleable liquid-propellant rocket engines can be used for planetary entry and descent, space rendezvous, orbital maneuvering including orientation and stabilization in ...
